Process for the separation of a liquid or liquids from another liquid or liquids, or from a solid or mixture of solids, with the minimum energy required for separation and recovery and recovered for re-use within the process

Abstract

A vaporization-condensation process using the refrigerant cycle (heat pump) for energy recycling between the vaporization and condensation processes with the refrigerant heat absorption/rejection capacity maximized to minimize installed power by controlling the system operating pressure (absolute) and allowing for the recovery of the condensable liquid vaporized, directly, indirectly, and within the seal liquid of the liquid ring pump if included in the system to; provide the less costly operating system feasible, recover one liquid from another, remove a liquid or liquids from a solid, purify water and, eliminate or minimize gas admission to the environment.

What I claim as my invention is:  
     
         1 . A process utilizing a heat pump to separate and recover a liquid or liquids from other liquids, solids or mixtures of liquids and solids,  
     
     
         2 . A heat pump system as in  claim 1  were the necessary energy required to vaporize the liquid or liquids is provided by the rejected heat of the heat pump used to absorb the energy removed while condensing the liquid or liquids during liquid recovery including heat pump power,  
     
     
         3 . A heat pump system as in  claim 1  operating at an absolute pressure that maximizes the Coefficient of Performance of the compressor by reducing both the required vaporization and condensation temperatures for the liquid or liquids being separated.  
     
     
         4 . Establishment and maintenance of the absolute pressure of  claim 3  using a liquid ring pump for the removal of non-condensable gases whose seal liquid may or may not be the same as that of the liquid or liquids being recovered.
